...with players who have incredible clubhead lag (for eg. on the downswing w/ Hogan, or Garcia), does that mean they are NOT bending their right wrist greater than impact fix (and impact) during the swing?
Welcome aboard, FeverPowerful. Good to have you here.
And thanks for the FGI quarantine heads-up. I went there for the first time today, and you were right. Never again.
Now, regarding your Right Wrist question, I know your post was essentially addressed to Chuck, and I'm sure he will respond.
Until then, though, two points:
First, the Left Wrist cocks (4-B-2) but the Right Wrist never does. It remains Bent (4-A-2) and Level (4-B-1) throughout the Stroke. This maintains the precision alignment and structure of the Power Package (6-B-3-0-1).
Second, there are three types of Lag (6-C-0):
The "Clubhead Lag" that you refer to with Hogan and Garcia is Accumulator Lag. Both men have Clubhead Lag. And Pivot Lag, too. But the trailing of the Club behind the Hands is not Clubhead Lag. This is a widely held misconception, even among long-time students of The Golfing Machine.
Nothing in The Star System of G.O.L.F. is more important than Lag. And yet the separate identities of the three types are not generally known, much less differentiated. Time permitting, I hope to post on this very important topic in the reasonably near future.
